.NET Backend Developer at InvestmentTribe building distributed financial data services and sub-100ms REST API endpoints.

Message

At InvestmentTribe, I architect and maintain .NET 8 backend services for real-time financial data pipelines. I use Domain-Driven Design and CQRS with MediatR to implement domain logic, and optimize critical REST API endpoints to sub-100ms response times.

At ExamRoom.AI, I developed enterprise applications for an AI-powered remote proctoring platform. I built REST APIs and SQL Server data solutions, integrated AWS Redshift for analytical reporting, and wrote xUnit and integration tests.

As a freelance .NET Developer for Connect Research, I designed data ingestion and processing solutions and built reusable API modules. I managed project work from requirements gathering through development, testing, and delivery.
